Hi Linda,
Thanks for the post.
This Guest user is a built in account that comes by default and it is safe to delete it. So go to Admin-->Users section and select the delete button at the end of this account. Or if you are using this account and want to update its password, then login using the username and password as "guest". Use local authentication. After logging in as Guest, you can use the "Change Password" link from the top right corner.
Hope this helps you. Do contact us if you have any other questions.
Thanks & Regards,
Ganesh
